Low-temperature resistivity and magnetoresistivity of cerium compounds

Abstract

The low-temperature resistivity and magnetoresistivity of cerium compounds are computed with a model describing both the crystalline field and Kondo effects, thus extending to low temperatures a previous calculation [Phys. Rev. B 5, 4541 (1972)]. The theoretical results can account for the resistivity data of cerium compounds, either those which order magnetically (such as ${\mathrm{CeAl}}_{2}$ or ${\mathrm{CeB}}_{6}$) or those which become nonmagnetic (such as ${\mathrm{CeAl}}_{3}$ or ${\mathrm{CeCu}}_{2}$${\mathrm{Si}}_{2}$) at low temperatures.
